VAR-200511-0314
Vulnerability from variot - Updated: 2025-04-03 22:16Cisco IP Phone (VoIP) 7920 1.0(8) listens to UDP port 17185 to support a VxWorks debugger, which allows remote attackers to obtain sensitive information and cause a denial of service. The Cisco 7920 wireless IP phone can provide Voice Over IP services over an IEEE 802.11b Wi-Fi network, which is similar to a cordless phone.
1) The SNMP service that runs on the IP phone uses fixed read-only and read-write community strings of "public" and "private", which cannot be changed by the user. This can be exploited to retrieve and modify the device configuration, including stored user data such as phone book entries by sending SNMP GetRequest or SetRequest to phone.
SOLUTION: Apply firmware update. http://www.cisco.com/warp/public/707/cisco-sa-20051116-7920.shtml#software
